It might be difficult to prove that there is direct punishment, but experience proves that the results of sin are often very bitter and painful. Sometimes they are felt in the body, when the sins of youth bring on disease which lasts all through life. They are often seen in the cases of Christians who set a bad example before their conversion, and they grieve when they see young people, whom they led into evil, grow worse and worse. The results of the sin of neglecting the training of children are frequently very sorrowful. The child grows up and falls into sin, and then the parent suffers remorse, as he feels that if he had only done his duty before it was too late, the child might have been saved. In many other ways, by natural law, sin works its own punishment.
